OUT1

Power

Output

H-Bridge Output 1

Source of high-side MOSFET1 and drain of low-side MOSFET1.

Logic Input

Disable Input 2

(Active Low)

When D2 is logic LOW, both OUT1 and OUT2 are tri-stated. (Schmitt trigger

input with ~80

µA sink so default condition = disabled.)

18–20,

22–24

PGND

Power

Ground

Power Ground

High-current power ground pins must be connected together physically as

close as possible and directly soldered down to a wide, thick, low resistance

ground plane on the PCB.

Logic

Output -

Open Drain

Status Flag

(Active Low)

Open drain active LOW Status Flag output (requires an external pullup resistor

to VDD. Maximum permissible load current < 0.5 mA. Maximum VCEsat

< 0.4 V @ 0.3 mA. Maximum permissible pullup voltage < 7.0 V.)

Logic Input

Disable Input 1

(Active High)

When D1 is logic HIGH, both OUT1 and OUT2 are tri-stated. Schmitt trigger

input with ~80

µA source so default condition = disabled.

OUT2

Power

Output

H-Bridge Output 2

Source of high-side MOSFET2 and drain of low-side MOSFET2.

CCP

Analog

Output

Charge Pump

Capacitor

External reservoir capacitor connection for internal charge pump; connected to

VPWR. Allowable values are 30

νF to 100 νF. Note This capacitor is required

for the proper performance of the device.
